To aZZ whom it may concern.-

Be it known that I, EUGENE MOREAU, a citi zen of the Republic of France, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Perforating Cones and the Like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to punching metal.

The" object of this invention is to perforate by a rapidly-operating machine bodies which have a constantly-varying diameter from one end to the otheras, for instance, cones.

Furthermore, the object is to perforate by means of machinery cones and similar bodies continuously in such manner that each perforation shall be an equal distance from the adjacent ones, in order that the web shall be uniform throughout.

With these objects in view the invention resides in a machine for perforating cones or other curved bodies, comprising a die, a die-holder, which is set at an angle coincident with the surface of the cone or other curved body to be perforated, and a punching-tool designed to descend upon the body lying upon the die.

Furthermore, the invention comprehends mechanism for giving the cone or other curved body a rotary motion and for imparting a longitudinal motion to the punching-tool and the die-holder.

Furthermore, the invention comprehends a machine comprising a die, a die-holder arranged at an angle coincident with the surface of the cone or other curved body to be perforated,areciprocating punching-tool, aholder for retaining thecone in proper operative position, and means for imparting a rotary motion to the holder and a longitudinal motion to the punching-tool and die; and, finally, the invention resides in various novel details of construction whereby the objects of the invention are attained and the proper operation of the parts is insured.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is aplan view of the machine made in accordance with my invention. Fig. 2 is an end elevation of the machine. tional view showing the bed-plate of the ma chine and the slide carrying the punch and its standard,'the section being taken on the line a: w of Fig. 1. Fig. 4 is a side elevation of the machine. Fig. 5 is a sectional detail view showing the inclined mandrel and the holder for the body to be perforated. Fig. 6 is asectional detail view showing a portion of the sliding plate carrying the punching-tool and illustrating the means for regulating the speed with which the sliding plate travels. Fig. 7 is an elevation of a cone of proper shape to be perforated by my machine. Fig. 8 is an elevation of the same, showing a portion of the surface as perforated, the perforationsbeing shown as very much enlarged to show them more perfectly and their relative arrangement. Fig. 9 is a side view of a cone, the whole of the surface excepting the base being shown perforated, and the perforations being shown enlarged, in order more perfectly to illustrate their arrangement.

In the drawings, A represents a bed-plate having a groove or a way, a, in which slides a plate, B, retained in position by the caps a and a secured to the bed-plate by suitable screws. Mounted upon the sliding plate is a curved arm, 13, having a base, 12, secured to a sliding plate by means of screws. Upon this arm is a lever, 13*, pivoted at a point, 1;, provided at one end with a plunger, I)", carrying a punching-tool, I), and provided at the other end with a bowl, b, upon which bears the cam which raises the lower end of the lever, and consequently depresses the upper end carrying the punching-tool. On the inside of the arm B is a projection, b carrying the connection I), on which is mounted an arm or mandrel, If. This is, as shown, so placed that the die carried by it is at an angle coincident with the generatrix of the cone to be perforated. The arm or mandrel b is provided at its outer end with an upward projection having an indentation forming a die to accomplish, in connection with the punch, the perforation of the surface of a cone or other body.

Upon the opposite side of the bed-plate to that upon which the sliding plate Bis mounted is a screw'shaft, O, carrying a box, 0, to which is attached a lever, D, passing over the slid- Fig. 3 is a secing plate, to which it is connected by means of a screw, d, and a plate, d, set in a dovetailed groove, (1, cut transversely in the sliding plate. The lever is slotted, as shown, and in the slot moves a plate, (1, having a circular opening, in which rests a projection, d, from the plate (l'-'. The position of theplated in the dovetailed groove is regulated by the screw (1, which is turned after the plate is set in the desired position to press against the bottom of the dovetailed groove, thereby forcing the plate against the inclined sides of the groove and retaining it in position. The function of the lever D is to cause the sliding motion of r the plate B from the screw-shaft O, and the speed with which the plates slide is regulated by the position of the plate (7? in the dovetailed groove of the sliding plate. Near the inner end of the screw-shaft is mounted a'bracket, F, having an opening through its upper portion, in which is mounted a hollow bearing,f, carrying a gear-wheel, f, meshing with apinion, 1', upon the screw-shaft. The bushingf extends through the bracket and its cndf is designed to enter the base of the cone to be perforated, and a collar,]", designed to be adjusted around the cone to holditin place upon the bushing during the operation of punching, is provided. The mandrel Z) passes through thehollow bushing, and its end b rests against the inner surface of the cone to be perforated, the bushing and mandrel being arranged at such an angle that as the mandrel moves longitudinally its end 2) moves in a line with the inner surface of the cone.

Mounted in suitable hearings on the bedplate of the machine is a shaft, G, provided at its outer end with a crank, G, or with abandwheel in case the machine is to be run by power. Upon this shaft are mounted two cams, r and g. The first of these cams is ar ranged beneath the lower end of the lever B" and acts upon the bowl placed at its lower end. The form of this cam is such that two movements of the lever are caused at each revolution of the shaft. The cam g at the outside of the machine bears twice in its revo lution against the lever H, pivoted upon the frame of the machine, and dependent in such position that its lower end bears against a block, Ill, which is connected to a rack, IF. This rack H meshes with a gear-wheel, II, mounted loosely upon the end of a screw shaft. Fixed to the screw-shaft outside of the gear-wheel H is a disk, H, provided with a reduced portion, 72, upon which bear the ends of the fingers 71, attached to the gear-wheel H, providing a simple clutch device for communieating motion from the rack to the screw 0. In the operation of this clutch, when the rack is moved by the cam g away from said cam, the clutch-fingers engage the disk and give the screw-shaft a partial revolution, and as the engaging part of the cam passes from coir tact with the lever H the rack is returned to its normal position by means of a coiled spring,

h". The block H is provided with a projection, it, which rests in a guide or way inv a block, it", in order to hold it against false mo tion.

I represents a tapering projection from the sliding plate 11, which extends beyond the bed'plate of the machine and bears against the block H. The function of this projection is to regulate the distance which the rack moves when giving an impulse by the cam g, and thereby regulating the distance which the bedplate, and consequently the punch and mandrel, move during each operation-that is to say, along movement of the rack is per mitted while the narrow portion of the cone is being perforated, and a gradual decreasing movement is allowed as the larger portion of the cone is operated upon, in order that the number of the perforations commensurate with the circumference being perforated shall be made.

The screwshaft is provided with a crank, h, for returning the parts to their normal po sition after the cone has been perforated.

H represents a spring-brake, its end to hold the disk H against false movement.

In the operation of the machine the parts are placed in their normal position, with the mandrel at such a point that its end is beneath that portion of the cone which is first to be perforated, and power is applied,giving motion to the rack, and therethrough to the screw-shaft G of the machine. At each complete revolution of the shaft two impulses are given to the rack, and through it to the screw shaft, thus imparting a rotary motion to the cone placed upon the hollow bushing, and also giving a sliding movement to the bed-plate carrying the arm supportingthe punching-tool. This rotary movement of the cone and sliding movement oft-he tool are so regulated and timed in relation to the punching or perforating operation that the perforations are made in a spiral line, beginning at the apex of the cone and terminating at any suitable point near its base. The parts are so accurately formed and arranged that a uniform space is left between each perforation and a web uniform throughout formed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
